Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline dredging, and particularly relates to a pipeline dredging and silt cleaning device. Background Art

[0002] Pipeline dredging generally refers to the dredging of household sewer pipes, toilet pipes, and industrial pipeline cleaning. The pipeline dredging work mainly includes removing the silt, garbage and other blocking substances in the pipeline, and then flushing out the accumulated water and dirt in the pipeline through equipment such as high-pressure water guns. During the pipeline dredging process, a silt cleaning device is required.

[0003] In the Chinese utility model patent with the publication number of CN221184052U, a pipeline rapid silt cleaning and dredging device is disclosed. By screwing the screw rod, the screw rod drives the shaft sleeve to slide back and forth in the hollow operating rod. The shaft sleeve drives the first sliding rod to squeeze the inner wall of the first chute, driving the rotating shaft to rotate. The rotating shaft drives the rotating plate to rotate. The rotating plate squeezes and pushes the second sliding rod through the second chute, thereby pushing the support rod to move. The movement of the support rod will change the position of the scraper, enabling the device to adapt to pipelines with different diameters, and the operation is convenient and simple.

[0004] After retrieval and in combination with the actual pipeline dredging work, it is found that the pipeline silt cleaning and dredging device proposed in the above comparative document still has some defects and deficiencies in actual application: the device lacks a flushing function and cannot be flushed in time after silt cleaning. Moreover, it is necessary to manually rotate the device to scrape the silt, which is time-consuming and laborious, and the efficiency of silt cleaning is low and the speed is slow. Therefore, it is urgent to improve the existing pipeline dredging and silt cleaning device and provide a pipeline dredging and silt cleaning device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pipeline dredging and silt cleaning device with reasonable design, simple structure, having a flushing function, and being convenient for automatically controlling rotation and scraping mud, and more efficient in silt cleaning, aiming to solve the problems existing in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A pipeline dredging and silt cleaning device includes a hollow pipe. The bottom end of the hollow pipe is fixedly communicated with a water storage pipe. Scraping mud components are symmetrically arranged on the left and right sides of the water storage pipe. The outer bottom end of the hollow pipe is threadedly sleeved with an adjusting sleeve. A locking bolt is threadedly installed on the front outer wall of the middle part of the adjusting sleeve. A rotating ring is sleeved on the outer bottom end of the adjusting sleeve through a bearing. Concave frames are symmetrically fixed on the left and right sides of the rotating ring. A handle is sleeved on the outer side of the top end of the hollow pipe through a bearing. A driving component is installed on the inner side of the right end of the handle.

One ends of both the first support rod and the second support rod are hinged to the water storage pipe, and the other ends of both the first support rod and the second support rod are hinged to the scraping plate.

[0009] As a preferred embodiment, the first support rod and the second support rod are equal in length and always parallel to each other, the scraping plate is always in a vertical state, and the end of the concave frame away from the rotating ring is slidably guided inside the through groove.

[0010] As a preferred embodiment, inclined surfaces are symmetrically provided on the outer wall of the water storage pipe, and a plurality of spray heads are equidistantly installed on the outer surfaces of the two inclined surfaces along their lengths.

[0011] As a preferred embodiment, the driving assembly includes a motor, a conical tooth and a conical tooth ring. The motor is fixedly installed on the inner wall of the right end of the handle. The output end of the motor is fixedly connected to the conical tooth. A conical tooth ring is meshed and connected to the lower left of the conical tooth. The conical tooth ring is fixedly sleeved on the outer side of the top of the hollow pipe. The diameter length of the conical tooth is only one-half of the diameter length of the conical tooth ring.

[0012] As a preferred embodiment, a threaded structure is provided on the outer surface of the bottom end of the hollow pipe, and a rotary joint is installed between the hollow pipe and the connecting pipe.

[0024] The following described embodiments are only a part of the embodiments of the present invention and do not represent all embodiments consistent with the present invention. Now, in conjunction with the drawings, the exemplary embodiments are described as follows:

[0025] As Figures 1-4 shown, the pipeline dredging and silt cleaning device of the present invention includes a hollow pipe 1. The bottom end of the hollow pipe 1 is fixedly communicated with a water storage pipe 2. Sludge scraping assemblies 3 are symmetrically arranged on the left and right sides of the water storage pipe 2. An adjusting sleeve 11 is threadedly sleeved on the outer side of the bottom end of the hollow pipe 1. A locking bolt 12 is threadedly installed on the front outer wall of the middle part of the adjusting sleeve 11. A rotating ring 13 is sleeved on the outer side of the bottom of the adjusting sleeve 11 through a bearing. Concave frames 14 are symmetrically fixed on the left and right sides of the rotating ring 13. A handle 6 is sleeved on the outer side of the top end of the hollow pipe 1 through a bearing. A driving assembly 7 is installed inside the right end of the handle 6. A connecting pipe 8 is fixedly installed through the middle part of the top end of the handle 6. The top end of the connecting pipe 8 is fixedly communicated with a hose 9.

[0026] On the basis of the above structure, the sludge scraping assembly 3 includes a first support rod 31, a through groove 32, a second support rod 33 and a scraper 34. A through groove 32 is formed inside the first support rod 31. A second support rod 33 is arranged directly below the first support rod 31. One ends of both the first support rod 31 and the second support rod 33 are hinged to the water storage pipe 2, and the other ends of both the first support rod 31 and the second support rod 33 are hinged to the scraper 34.

[0027] On the basis of the above structure, the first support rod 31 and the second support rod 33 are equal in length and always parallel to each other. The scraper 34 is always in a vertical state. One end of the concave frame 14 away from the rotating ring 13 is guided and slides inside the through groove 32.

[0028] In this embodiment, the use of the first support rod 31 and the second support rod 33 that are equal in length and always parallel to each other facilitates adjusting the distance between the scraper 34 and the water storage pipe 2, so that the device can be applied to pipe dredging with different inner diameters.

[0029] On the basis of the above structure, inclined surfaces 4 are symmetrically arranged on the outer wall of the water storage pipe 2, and a plurality of nozzles 5 are equidistantly installed on the outer surfaces of the two inclined surfaces 4 along their lengths.

[0030] In this embodiment, the use of a plurality of nozzles 5 facilitates flushing the inner wall of the pipe while dredging, making the dredging more thorough and efficient.

[0031] On the basis of the above structure, the driving assembly 7 includes a motor 71, a conical tooth 72 and a conical tooth ring 73. The motor 71 is fixedly installed on the inner wall of the right end of the handle 6. The output end of the motor 71 is fixedly connected to the conical tooth 72. A conical tooth ring 73 is meshed and connected to the lower left of the conical tooth 72. The conical tooth ring 73 is fixedly sleeved on the outer side of the top of the hollow pipe 1. The diameter length of the conical tooth 72 is only one-half of the diameter length of the conical tooth ring 73.

[0032] In this embodiment, by starting the motor 71 to control the rotation of the conical tooth 72, the conical tooth ring 73 meshed with the conical tooth 72 can drive the hollow pipe 1 to rotate uniformly, achieving the technical effect of automatic rotary sludge scraping, making the device more convenient and labor-saving to use.

[0033] On the basis of the above structure, a threaded structure is provided on the outer surface of the bottom end of the hollow pipe 1, and a rotary joint 10 is installed between the hollow pipe 1 and the connecting pipe 8.

[0034] In this embodiment, the use of the rotary joint 10 facilitates ensuring the stable flow supply of water while the hollow pipe 1 rotates stably.

[0035] The working principle of the present utility model is as follows:

[0036] During use, first manually rotate the adjusting sleeve 11 to drive the rotating ring 13 to vertically move downward along the threaded section at the bottom of the hollow tube 1. At this time, the concave frames 14 on both the left and right sides of the rotating ring 13 can squeeze the first support rod 31 with a through groove 32 formed inside, and with the cooperation of the second support rod 33, it can push the scraping plate 34 to move away from the water storage pipe 2, facilitating dredging of pipes with different inner diameters. After adjustment, the sludge scraping assembly 3 can be inserted into the pipe, and the scraping plate 34 can be made to fit the inner wall of the pipe. During dredging, the motor 71 can be started to control the rotation of the conical tooth 72, and the conical tooth ring 73 meshing with the conical tooth 72 can drive the hollow tube 1, the water storage pipe 2, and the two sludge scraping assemblies 3 to rotate synchronously and evenly, thereby achieving the technical effect of automatic rotary sludge scraping. The device is more convenient and labor-saving to use, and the sludge scraping speed is faster;

[0037] During pipe dredging, one end of the flexible hose 9 can also be connected to an external water supply source, and clear water can be conveyed into the water storage pipe 2 through the flexible hose 9, the connecting pipe 8, the rotary joint 10, and the hollow tube 1. Subsequently, it can be pressurized and sprayed toward the inner wall of the pipe through a plurality of spray heads 5 provided on the outer surfaces of the two inclined surfaces 4, so that timely flushing can be carried out while rotating and scraping the sludge, and the dredging effect is better and the dredging is more thorough;

[0038] It should be particularly noted that the rotary joint 10 is an existing product, and its internal structure and specific working mode both adopt existing technical means, which is not the innovation direction of this case, so it will not be elaborated further.

[0039] The above is only a preferred specific embodiment of the present utility model, and it is not used to limit the protection scope of the present utility model; all equivalent changes, modifications, substitutions, and variations made by those skilled in the art in this technical field according to the concept of the present utility model on the basis of the existing technology through logical analysis, reasoning, or limited experiments shall fall within the protection scope determined by the claims.
